Ok, I got a $50 Steam card for Christmas. Throw some recommendations at me. lol

For games in general?

Well, you can get the entire Bioshock pack for like $15 which includes Bioshock/Bioshock2/Bioshock Infinite. L4D2 is free right now, so get that immediately! Uhh.. Skyrim is suuuuper cheap, like $8, and that's an amazing game. Lessee.. what else..

I'm not sure what kinda games you're into, but Starbound is like a Terraria meets Minecraft and supposed to be great and it's only $15. I have it but haven't played it yet. Uhhh.. if you are into zombie survival stuff you could check out Day Z ($29.99). It's in Alpha and sort of buggy but a lot of DCers play it and like it a lot.
